La construction de réponses à des problèmes impossibles

Abstract: Cet article se propose d'illustrer la dynamique de construction de réponses à des problèmes impossibles. En fonction du cadre conceptuel, situé à l'articulation de problématiques psychologiques et didactiques, un modèle d'analyse des différents plans de rationalité en jeu dans la fabrication des réponses des élèves est présenté et discuté. Le choix de problèmes impossibles de différentes complexités s'avère ainsi un moyen de recherche particulièrement fructueux pour montrer les effets de contrat (expérimental … Show more

“…According to this model, the mathematical procedures the student applies to solve a problem are influenced by both their interpretation of the task and perception of what the teacher is asking. The theory of didactic situation (Brousseau 1988;Schubauer-Leoni and Ntamakiliro 1994) explains that a student's comprehension of a problem can be affected by the didactic contract, which includes their perception of the teacher's intentions for the task. This theory does not explain why some students are affected by the didactic contract phenomenon and others are not.…”

“…A full and flexible understanding of the additive structures in word problems is identified by researchers (Barrouillet and Camos 2002;Checkley 2006;Riley and Greeno 1988;Vergnaud 1982) as a crucial skill required to become better problem solvers. According to a number of studies (Barrouillet and Camos 2002;Brousseau 1988;Chevallard 1988;Riley et al 1984;Schubauer-Leoni and Ntamakiliro 1994;Vergnaud 1982;Xin 2007), many factors can potentially lead to students experiencing difficulties in developing this skill. Researchers are still looking for more effective teaching solutions and strategies (Jackson et al 2012;Mellone et al 2014).…”

“…-un rapport public, qui se donne à voir dans une institution ; il correspond à ce que les sujets « mettent en visibilité à travers divers canaux et systèmes de signiiants » (Schubauer-Leoni & Ntamakiliro, 1994) ; -un rapport privé, « invisible dans cette institution et donc [qui] échappe à l'évaluation de conformité par cette institution » (Chevallard, 1992), car élaboré par l'individu « pour lui-même et qu'il ne juge pas utile ou nécessaire de rendre visible » (Schubauer- Leoni & Ntamakiliro, 1994) ; il peut le gérer à sa guise dans la mesure où il demeure privé, c'est-àdire où il n'empiète pas sur la sphère des actes « publics [dans cette institution] » (Chevallard, 1996). Notamment, un élève ne sera interpellé, didactiquement, que sur le rapport à un objet de savoir qu'il est capable de manifester en classe, et jugé à la conformité de ces manifestations au rapport oficiel 12 à cet objet de savoir déini par l'enseignant à un moment donné de la vie de la classe -tout le reste demeurant l'affaire privée de l'élève (Chevallard, 1992).…”

“…On the contrary, in everyday situations, prompted by uncertainties about the communication, the individuals can ask questions and propose hypotheses rather than responses, intentionally intervene in the course of the interaction and negotiate the potential meanings of the situation to ensure a certain intersubjectivity. As remarkably summarized by Schubauer- Leoni and Ntamakiliro (1994): "it is a question of identifying meanings attributed by the student and by the experimenter as a function of the contracts to which each of them is tacitly referring. It is therefore possible, in certain cases, to observe misunderstandings that are essentially due to the non-concomitance of the reference worlds of each of them" (p. 89, our translation).…”
